1. Although 90 percent of the population believes itself to be well informed about health care, only 20 percent knows enough about DNA. So apparently at least 80 percent of the population does not know enough about medical concepts to make well-informed personal medical choices or to make good public policy decisions about health care.
The argument’s reasoning is questionable because the argument fails to demonstrate that
A. those people who can understand news stories about DNA are able to make well-informed personal medical choices
B. more than 20 percent of the population needs to be well informed about health care for good public policy decisions about health care to be made
C. one’s being able to make well-informed personal medical choices ensures that one makes good public policy decisions about health care
D. an understanding of DNA is essential to making well-informed personal medical choices or to making good public policy decisions about health care
E. since 90 percent of the population believes itself to be well informed about health care, at least 70 percent of the population is mistaken in that belief.
答案：D
思路：本题的推论错误在于以偏概全，用对DNA的了解程度来考核well informed about health care的程度。据个例子，我们可否用掌握核物理知识的程度来考核对物理基本知识的掌握程度呢?显然不行!
A: 支持作者的观点
B: 无关
C: 无关
D: 本题的推论错误在于以偏概全，用对DNA的了解程度来考核well informed about health care的程度。据个例子，我们可否用掌握核物理知识的程度来考核对物理基本知识的掌握程度呢?显然不行!
E: 无关

4. The gray squirrel, introduced into local woodlands ten years ago, threatens the indigenous population of an endangered owl species, because the squirrels’ habitual stripping of tree bark destroys the trees in which the owls nest. Some local officials have advocated setting out poison for the gray squirrels. The officials argue that this measure, while eliminating the squirrels, would pose no threat to the owl population, since the poison would be placed in containers accessible only to squirrels and other rodents.
Which one of the following, if true, most calls into question the officials’ argument?
A. One of the species whose members are likely to eat the poison is the red squirrel, a species on which owls do not prey.
B. The owls whose nesting sites are currently being destroyed by the gray squirrels feed primarily on rodents.
C. No indigenous population of any other bind species apart from the endangered owls is threatened by the gray squirrels.
D. The owls that tare threatened build their nests in the tops of trees, but the gray squirrels strip away back from the trunks.
E. The officials’ plan entails adding the poison to food sources that are usually eaten by rodents but not by other animals.
参考答案：B
思路：本题的错误在于，作者提出一种解决问题的方法，但忽略了他的副作用或反作用，从而没有从根本上解决问题或引出其他更重要的问题。
A：无关 red squirrel
B：如果rodents是owls的主要食物，那末毒死rodents将更严重的减少owls的数量。
C：无关 Here the concerned object is the owl, not the other birds
D：无关
E：无关选项 Without further information about the rodents, this choice does not bother the argument
Questions 5-6
Sales manager: Last year the total number of meals sold in our company restaurants was much higher than it was the year before. Obviously consumers find our meals desirable.
Accountant: If you look at individual restaurants, however, you find that the number of meals sold actually decreased substantially at every one of our restaurants that was in operation both last year and the year before. The desirability of our meals to consumers has clearly decreased, given that this group of restaurants---the only ones for which we have sales figures that permit a comparison between last year and the year before---demonstrates a trend toward fewer sales.
5. If the sales figures cited by the accountant and the sales manager are both accurate, which one of the following must be true?
A. The company opened at least one new restaurant in the last two years.
B. The company’s meals are less competitive than they once were.
C. The quality of the company’s meals has not improved over the last two years.
D. The prices of the company’s meals have changed over the past two years.
E. The market share captured by the company’s restaurants fell last year.
参考答案：A

遇到这种题，只要列出公式即可解决。
6. Which one of the following, if true, most seriously calls into question the accountant’s argument?
A. The company’s restaurants last year dropped from their menus most of the new dishes that had been introduced the year before.
B. Prior to last year there was an overall downward trend in the company’s sales.
C. Those of the company’s restaurants that did increase their sales last year did not offer large discounts on prices to attract customers.
D. Sales of the company’s most expensive meal contributed little to the overall two-year sales increase.
E. Most of the company’s restaurants that were in operation throughout both last year and the year before are located in areas where residents experienced a severe overall decline in income last year.
Sales Manager: the total number of meals sold last year much higher consumers desire our meals
Accountant: the number of meals sold by every restaurants operating these two years actually decreased last year from the year before (事实) the desirability of our meals has decreased ( conclusion) a trend toward fewer sales (conclusion)
1， 不同的取样，Sales Manager depends on the total number of meals sold in the company in the last year, while Accountant depends on each of 2-year-history restaurant;
2， 论据与结论之间没有必然的联系，却被当成充分条件。他因可以解释结论。
A. Reason to explain why the sale of each sample restaurant decreased last year. (无关)
B. 总公司前年的下降不能否定去年的下降，也不能支持。(无关)
C. 那些去年销量不降反增的公司是因为没有降价太多。不降反增的公司与下降的公司是两个不同的集合，描述对象不正确。如果我们推出那些下降的公司是因为降价太多，也只能是给出一个原因来解释为什么下降。 (无关)
D. 公司最贵的招牌菜并没有给公司带来销售的增加。也属于一个解释，解释为什么总量会下降。但与Accountant 的观点并没有直接的联系。既没有针对描述对象：2-year-history restaurant，也没有削弱论据与结论之间的必然联系。
E. 答案。针对描述对象：2-year-history restaurant，他因：a severe overall decline in income
时间的一致：last year.
